Arduino RC Car help

Hello fourm!

I want to wire into a rc receiver board I found that has a SM6130 (B) chip on it. I can't find a pin out and the motor wires have fallen off. Can anyone help me find the pin out and the wire's position.
Photos are at (Yes they are bad focus, will post more when phone doesn't crash :confused: )

PS. No power is required for the circuit (via the chip).
